Solar pv removed and reinstalled - now running at less power

[kkkkk]

Hi all - an outbuilding with solar panels - they have been removed to replace the roof, and replaced 4 months later with the system isolated and now reactivated. Previously the system was running at about 1.8kw but now it is running at round about 2A 500w - with occasional leaps to 1.6kw and then back again - my knowledge is limited - so any help would be greatly appreciated - thanks in advance

Hi - thanks for the replies - is there a specific reset I can do? I thought powering it all back on was the reset.

AC/DC -OFF
DC/AC -ON

Yes, all ok thanks - any further ideas appreciated

Assuming that you had someone who knows what they are doing with solar panels remove and refit them, and it was not your roofers, get them back to test and recheck the connections.
